Luminous Blue Variable Star
Luminous blue variable stars (LBVs), also known as S Doradus variables, after S Doradus, one of the brightest stars of the Large Magellanic Cloud, are extremely luminous blue variables that exhibit long, slow changes in brightness, punctuated by occasional outbursts in brightness during substantial mass loss events (e.g. Eta Carinae, P Cygni). They are extraordinarily rare. The General Catalogue of Variable Stars only lists 20 objects as SDor and a number of these are no longer considered to be LBVs.

Famous quotes containing the words luminous, blue, variable and/or star:
“A quibble is to Shakespeare what luminous vapours are to the traveller: he follows it at all adventures; it is sure to lead him out of his way and sure to engulf him in the mire.”

And I are one.”

“There is not so variable a thing in nature as a lady’s head-dress.”

“The eastern light our spires touch at morning,
The light that slants upon our western doors at evening,
The twilight over stagnant pools at batflight,
Moon light and star light, owl and moth light,
Glow-worm glowlight on a grassblade.
O Light Invisible, we worship Thee!”
—T.S. (Thomas Stearns)
